Description

Method and system for realizing wireless resource control

The present invention relates to a wireless communication technology, and more particularly to a method and system for implementing wireless resource control. Background technique

The communication between human beings (H2H, Human to Human) is realized by humans through the operation of the device, and the existing wireless communication technology is developed based on H2H communication. The narrow definition of Machine to Machine (M2M) is machine-to-machine communication. Broadly defined, it is a networked application and service based on intelligent interaction of machine terminals. M2M is an information-based solution for customers based on intelligent machine terminals and using multiple communication methods as access methods to meet customers' information needs for monitoring, command and dispatch, data acquisition and measurement.

The development of wireless technology is an important factor in the development of the M2M market. It breaks through the space-time constraints and geographical barriers of traditional communication methods, freeing enterprises and the public from cable shackles, allowing customers to control costs more effectively, reduce installation costs and is simple to use. Convenience. In addition, the growing demand is driving M2M to move forward. However, contrary to the continuous growth of information processing capabilities and network bandwidth, the means of information acquisition is far behind, and M2M satisfies people's needs very well. With M2M, people can monitor the external environment in real time and achieve a wide range of Automated information collection. Therefore, M2M applications include industrial applications, home applications, personal applications, etc. Among them, industry applications include traffic monitoring, alarm systems, marine rescue, vending machines, car payment, etc. Home applications include automatic meter reading, temperature control, etc. Applications include life testing, remote diagnosis, and more.

M2M objects are machine-to-machine, person-to-machine, and data communication between one or more machines is defined as Machine Type Communication (MTC), in which case human interaction is less required. The machine participating in the MTC is called the MTC device or the MTC terminal (MTC). Device ). The MTC device can communicate with other MTC devices or MTC servers via a Public Land Mobile-Communication Network (PLMN).

? ! After the MTC application is applied, the existing communication system can be optimized according to its characteristics to meet the requirements of the MTC application, and does not affect the ordinary H2H devices in the existing network, such as the user equipment (UE, User Equipment). Some notable features of M2M applications are: MTC devices are numerous, the amount of data transmitted per time is small, the transmission interval is large, and some MTC devices are relatively fixed in position. According to statistics, there will be 3,000 MTC devices installed in a certain urban area. If so many MTC devices initiate random access, such as fires, earthquakes, etc., they will bring alarms to the network. Great impact. Generally, multiple base stations are connected to the same core network element, such as a Mobility Management Entity (MME). When many MTC devices in all base stations need to access the network, for example, after power off, the power is restored. All MTC devices need to be registered in the network, which will cause the MME to bear huge signaling impact and may even cause overload.

When a large number of MTC devices access the network, they will occupy a large amount of wireless resources. If the number of MTC devices accessing the network is too large, the wireless resources will be overloaded, which will adversely affect the access of the ordinary H2H devices to the network. Since the radio resource is limited (or determined) for any cell, in a Long-Term Evolution (LTE) system, the radio resource can be represented by a Physical Resource Block (PRB) protocol. Specify N _b single-carrier frequency division multiple access (SC-FDMA, Signal-Carrier Frequency) in the time domain

Division Multiple Access) The symbol and the consecutive N subcarriers in the frequency domain are defined as one PRB (uplink), where N _b is the number of SC-FDMA symbols included in one uplink slot, and N is the resource block size in the frequency domain. The uplink resource of the entire cell may be represented by i N subcarriers, where the value of A is determined by the uplink transmission bandwidth configured in the cell, and satisfies N ' ^UL ≤ A ≤ A ^X ' ^UL , where the minimum uplink bandwidth N ' ^UL = 6 and maximum uplink band The protocol defines a downlink physical resource block, where N _b consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols and N _s consecutive frequency domain subcarriers are defined as one physical resource block ( Downstream), where N _b is the number of OFDM symbols included in one downlink slot, and N is the resource block size in the frequency domain. The downlink resource of the entire cell may be represented by A^A subcarriers, where the value of A is determined by the downlink transmission bandwidth configured in the cell, and the N supported by the protocol is also between 6 and 110. When the number of MTC devices in the accessing cell is too large, a large number of physical resource blocks are inevitably occupied, which results in a limited number of physical resource blocks available to ordinary users, which affects the transmission efficiency of ordinary users accessing the network.

In the existing protocol, the base station needs to perform some measurements to dynamically implement access control according to changes in the load. The measurement of the existing base station includes the use of the PRB, the number of activated terminals, and the total throughput of the terminal, among them, PRB The use includes the total PRB usage, the PRB usage per traffic class, and the PRB usage for SRB. Physical resource blocks used by the uplink and downlink common control channels (DL PRB usage for Common Control Channels, UL PRB usage for Common Control Channels).

Existing base stations have implemented measurements on PRB, such as:

For the total physical resource block used, the protocol is defined as duration T (this period of time)

Μ\(Τ) _{1 ΛΛ} Also known as measurement time) The average total physical resource block ratio used Μ(Γ) = ^y *ιοο

Ρ(Τ)

In the middle, Μ1 (Γ) refers to the sum of all physical resource blocks used for transmission in the uplink and downlink, and refers to the total physical resource block in the duration ;; the physical resource block used in each service level is defined as Μ(·):

M _C , r) refers to the total physical resource block used for each service level in duration T, and refers to the total physical resource block within the duration Τ. Here, each service level is classified according to the QoS Class Identifier (QCI), and the QCI is used to specify the definition in the access node. Control bearer-level packet forwarding mode (such as scheduling weight, admission threshold, queue management threshold, link layer protocol configuration, etc.);

The physical resource blocks used by the signaling radio bearers and the physical resource blocks used by the common control channel are similar to the above two definitions, and are not described here.

However, the measurement of the existing base station is directed to all the terminals, and the base station cannot know the status of the use of the radio resources by the H2H device, and thus cannot effectively prevent the MTC device from occupying a large amount of radio resources. In this way, if the number of MTC devices accessing the network is large, it may hinder the access of ordinary users, which seriously affects the access experience of ordinary users. Summary of the invention

In view of this, the main purpose of the present invention is to provide a method and system for implementing radio resource control, which can effectively prevent the MTC device from occupying a large amount of radio resources, thereby avoiding the shortage of radio resources available to ordinary users and ensuring the connection of common users.

FIG. 1 is a schematic flowchart of a method for implementing radio resource control according to the present invention. As shown in FIG. 1, the method includes the following steps:

Step 100: The base station measures the number of activated terminals of different attributes. The specific implementation of the measurement therein is a matter of skill in the art and is not intended to limit the scope of the invention.

Different attribute terminals refer to different types of terminals, including MTC devices, and/or H2H devices; or, different attribute terminals refer to terminals that initiate delay service, and/or terminals that do not allow delay services;

Or, different attribute terminals refer to terminals that initiate different priority services;

Or, different attribute terminals refer to terminals of different priorities;

Or, different attribute terminals refer to roaming terminals, and/or non-roaming terminals; Or, different attribute terminals refer to terminals belonging to different groups.

In this step, the base station learns the attributes of the terminal through the reporting of the terminal, for example, when the terminal accesses the access request, or when the connection establishment is completed, the signaling is reported to the base station through the connection completion signaling.

Step 101: The base station controls the corresponding attribute terminal according to the measured number of activated terminals. Specifically, it may include access control, and/or load balancing control, and the like. among them,

In this step, the base station performs access control according to the measured number of activated terminals, including: the base station separately sets the threshold number of active terminals of different attribute terminals in advance, if the number of activated terminals belonging to a certain attribute terminal reaches or exceeds the set value. Threshold, then, the base station rejects the terminal accessing the network belonging to the attribute, or the base station releases part or all of the connected terminals belonging to the connected state (the specific implementation may be performed according to a preset policy, such as a base station When receiving the access request belonging to the terminal of the attribute, sending a connection rejection signaling to the terminal to reject the access of the terminal; or the base station selects a terminal belonging to the attribute in a connected state, and sends a connection release letter to the terminal. Order, etc.)

In this step, the base station performs load balancing control according to the measured number of activated terminals. The base station sets the threshold number of active terminals of different attribute terminals in advance, and the base station sends the measured number or percentage of active terminals of the different attribute terminals to other base stations. Rate, and when the other base station selects the target cell for the terminal, according to the received number or percentage rate of the activated terminal of the terminal class to which the terminal belongs and the threshold value, the target cell that can satisfy the service requirement for the attribute terminal is selected.

It can be seen from the method of the present invention shown in FIG. 1 that the base station monitors the number of active terminals of different attribute terminals in real time, clarifies the radio resource information used by terminals of different attributes, and thus controls the access of terminals of different attributes, and avoids access of some terminals. When the network occupies a large amount of radio resources, other terminals cannot access the network smoothly and cannot successfully carry out services. In particular, the MTC device is effectively prevented from occupying a large amount of wireless resources, thereby avoiding the shortage of wireless resources available to ordinary users, ensuring the transmission efficiency of the ordinary user accessing the network, thereby improving the network negative. Load control capability.

Target cell.

The method of the present invention will be described in detail below with reference to the embodiments.

3 is a schematic flowchart of a first embodiment of a radio resource control method according to the present invention. In the first embodiment, it is assumed that in an LTE system, different attribute terminals, such as an MTC device and an H2H device, access the network through the cell 1 under the base station 1. And is connected. In order to implement load balancing, the base station 1 needs to measure the usage of the radio resources in real time. In this embodiment, the number of activated terminals is measured. As shown in Figure 3, the following steps are specifically included:

Step 300: The base station 1 sets the threshold number of activated MTC devices.

In the first embodiment, it is assumed that the base station 1 prevents the MTC device from using too many radio resources, causing the H2H device to access the network to be difficult to perform large-bandwidth services, and the base station 1 is preset with the threshold number of activated MTC devices. For example, 60.

Step 301: The base station 1 receives an access request of the terminal, and learns the attribute of the terminal. In order to assist the resource scheduling and access control of the base station 1, when the terminal accesses the network (here, through the cell 1), it needs to report its attributes, and the terminal may establish the connection request of the radio resource control (RRC, Radio Resource Control) connection request ( The attribute indicates that the attribute may also carry the attribute information in the RRC connection setup complete signaling. Here, the MTC device is set as an MTC device in the establishment cause of the RRC connection request.

Step 302: The base station 1 determines whether the MTC device can be allowed to access: if the activated MTC device number is lower than the set threshold, accept the access request of the MTC device, and then proceeds to step 303; otherwise, step 304 is performed.

Step 303: The base station 1 accepts the access request of the current MTC device, and measures the number of all active MTC devices in the cell at this time. End this process.

Step 304: The base station 1 rejects the MTC device currently requested to access.

In particular, if the base station 1 determines that the activated MTC device exceeds the predetermined number of MTC devices, it may also release some or all of the MTC devices in the connected state to free up sufficient resources to ensure the use of the H2H device.

In the first embodiment, if the MTC device in the connected state enters the idle state, the RRC connection is released, the method further includes: the base station 1 subtracting the number of the MTC devices, and obtaining the updated number of activated MTC devices. Then use this as a basis for judging whether a new MTC device can access the network.

In the first embodiment, the base station 1 may separately measure the number of MTC devices of each service class according to each service level established by the MTC device, and the base station 1 sets a threshold value of the number of MTC devices of different service levels, according to the threshold. Determine whether to allow new MTC devices to access the network.

According to the method of the embodiment shown in FIG. 1, the base station 1 reserves sufficient radio resources for the H2H device, thereby avoiding the problem that the H2H device is connected to the network by the MTC device, and the access delay is large and the transmission efficiency is low.

Second Embodiment, assuming that in an LTE system, an MTC device and an H2H device pass through a base station 2 The cell 2 under the jurisdiction of the network accesses the network and is in a connected state. In order to implement load balancing, the base station 2 needs to measure the usage of the radio resources in real time. In this embodiment, the number of activated terminals is referred to.

In the second embodiment, it is assumed that both the MTC device and the H2H device can initiate a delay tolerant service (or a service called delay tolerance), or a low priority service, corresponding to the MTC. The device and the H2H device can also initiate a service that does not allow delay, or a service with normal priority, such as a signaling call initiated by the terminal (mo-Signaling) or a data call initiated by the terminal (in the existing protocol) ( mo-Data) business. Moreover, in some scenarios, if the MTC device in the monitoring state detects an emergency, it can also initiate high priority access (high Priority Access). H2H devices can initiate high-priority services and emergency services. Emergency service is the highest priority service, which means that the terminal communicates with local emergency communication receiving centers such as police, fire, medical care and so on.

It is assumed that the base station 2 is preliminarily set with a threshold value of the number of active terminals allowing the delay service, and a threshold value for initiating the number of active terminals not allowing the delay service. The radio resource control method in this implementation includes:

The base station 2 measures the number of active terminals that initiate the allowable delay service, and the number of active terminals that initiate the service that does not allow the delay service;

The base station 2 compares whether the number of active terminals that initiate the allowed delay service reaches a preset threshold, and if so, the base station 2 rejects the allowed delay service initiated by the new terminal, or the base station 2 selects part of the allowed delay service. The MTC device or the H2H device releases the RRC connection of the part of the terminal, so as to effectively control the amount of resources used by the service terminal to allow the delay.

Other implementations of the second embodiment may also be:

The base station 2 measures the number of active terminals that initiate different priority services, and the base station 2 sets the threshold value of the number of active terminals for each priority service. When the number of active terminals used to initiate a certain priority service reaches the set gate When the limit is reached, the base station 2 rejects the establishment request of the priority service, or releases the terminal that has initiated the priority service; or The base station 2 measures the number of active terminals of different priorities, and the base station 2 sets the threshold of the number of active terminals of each priority. When the number of active terminals of a certain priority reaches the threshold, the base station 2 rejects the priority. The terminal accesses the network, or releases some of the accessed terminals of the priority. It should be noted that the terminal stores its own priority information (including low-priority terminals, normal-priority terminals, and high-priority terminals), and needs to pass when initiating a service request.

The RRC signaling sends the priority to which the RRC signaling belongs to the base station 2, and the base station 2 measures the number of activations of all the priority terminals according to the information; or

The base station 2 measures the number of active terminals used by terminals of different groups, and the base station 2 sets the threshold value of the number of active terminals of each group at the same time. When the number of active terminals of a certain group reaches the threshold, the base station 2 rejects The terminal belonging to the group accesses the network, or releases some or all of the terminals that have belonged to the group. It should be noted that different terminals may belong to different groups, and may belong to the same group. Each group has its own group name identifier. The base station 2 obtains the group name of the member by sending the RRC signaling through the terminal, or The core network is informed of the group name to which it belongs (specifically, the group name of the member network is known through the core network, when the core network authenticates the accessed terminal, the group name of the member is known, and then the core network informs the base station that the terminal belongs to the terminal. Group name), which in turn can measure the number of active terminals in different groups; or

The base station 2 measures the number of roaming active terminals and the number of non-roaming active terminals, and the base station 2 sets the threshold value of the number of roaming active terminals at the same time. When the number of roaming active terminals reaches the set threshold, the base station 2 Reject the access request of the roaming terminal, or release some or all of the roaming terminals. The local public land mobile network (HPLMN) network identifier is stored in the USIM (Universal Subscriber Identity Module) of the terminal, or an equivalent local public land mobile network (EHPLMN, The Equivalent Home PLMN identifies that the terminal can know the PLMN identity of the network to which the cell belongs in the system message of the currently visited cell, and can further determine whether it is a roaming terminal: if the terminal currently accessing the network is not the HPLMN, it indicates that the terminal is roaming. Terminal Or if the current network is neither HPLMN nor EHPLMN, it means that the terminal is a roaming terminal. The terminal can report to the base station 2 whether it belongs to the roaming terminal through RRC signaling, and the base station 2 can measure the number of roaming terminal activations and measure the number of non-roaming terminal activations according to the obtained information.

4 is a schematic flowchart of a third embodiment of a radio resource control method according to the present invention. In the third embodiment, it is assumed that in the LTE system, the base station 3 and the base station 4 are adjacent base stations, and there is an X2 interface between them. The cell 3 under the control of the base station 3 and the cell 4 under the base station 4 are mutually adjacent cells. Different H2H devices and different MTC devices access cell 3 and cell 4, respectively. The base station 3 and the base station 4 respectively measure the number of active terminals of different types of terminals in the respective jurisdictions. Since the terminal moves, in order to ensure that the terminal can smoothly switch to the adjacent cells, the base stations can interact in advance according to the method of the present invention. Information, so that the source base station can select a handover target cell with sufficient resources. As shown in Figure 4, it specifically includes:

Step 400: The base station 3 sends a resource status request (Resource Status Request) to the base station 4. In this step, the resource status request carries a report characteristic (Report Characteristics), such as requesting to report the number of activated terminals, or requesting to report the number of activated terminals of different types of terminals; and further including a reporting period, a cell requesting reporting Logo, etc.

Step 401: After receiving the resource status request, the base station 4 returns a resource status response (Resource Status Response) to the base station 3, and notifies the base station 3 that the base station 4 will implement the corresponding measurement, and reports the corresponding number of activated terminals to the base station 3.

Step 402: The base station 4 sends a resource status update (Resource Status Update) signaling to the base station 3, where the resource status update signaling includes the number of activated terminals of different types of terminals in the cell 4, that is, the number and activation of the activated MTC devices. The number of H2H devices; or the percentage of activated MTC devices (the percentage ratio refers to the ratio of the number of activated MTC devices to the number of active MTC devices allowed to be accessed by the base station 4, and other percentage rate means Similarly, no longer repeat) and the percentage of activated H2H devices. Step 403: The base station 3 performs the selection of the target cell according to the received resource status update signaling.

For example, a certain MTC device in the cell 3 of the base station 3 needs to be switched, and the base station 3 selects a target cell according to the measurement report reported by the MTC device. It is assumed that the candidate target cell in this embodiment includes the cell 4 (belonging to the base station 4). The cell 3 does not select the cell 4 as the target cell. On the other hand, if the base station 3 knows in step 402 that the number of MTC devices in the cell 4 is not overloaded and can meet the service requirements of the MTC device to be switched, the base station 3 can select the cell 4 as the target cell for handover.

It should be noted that there are other implementation manners in the third embodiment. For example, the base station 3 may request the base station 4 to send the number of active terminals of the roaming terminal and the non-roaming terminal. After the base station 3 obtains the information, when the terminal needs to switch, the base station may The roaming feature of the terminal selects a suitable target cell; or

The base station 3 may request the base station 4 to send the number of active terminals (or percentage ratios) for initiating the allowed delay service. After obtaining the information, the base station 3 may select a suitable target cell for the terminal when the terminal that initiates the allowed delay service needs to be handed over; Or,

The base station 3 can request the base station 4 to send the number of active terminals that initiate different priority services. After obtaining the information, the base station 3 can select a suitable target cell for the terminal that initiates different priority services.

With the method of the third embodiment, the number of active terminals that interact with different types of terminals between adjacent base stations, or the number of active terminals that implement the interaction of the roaming terminal, or the activation terminal that implements the interaction initiation delay service is implemented. The number, or the number of active terminals that initiate the different priority services are mutually activated. When the corresponding terminal needs to switch, the base station selects the target cell that meets the service requirement according to the obtained number of activated terminals, and avoids the RRC connection caused by the failure of the handover process. freed. In particular, when adjacent base stations interact with the number of activations of the MTC device, It indicates that the base station needs to properly control the MTC device, thereby avoiding the problem that the MTC device occupies a large amount of radio resources, and the ordinary user cannot successfully access the network and cannot obtain a satisfactory wireless service.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included. Within the scope of protection of the present invention.
